Right-click in the C drive window and open the Program Files directory.

Copy and paste the Microsoft Games folder from your flash drive to the Program Files directory.

Now open the Microsoft Games folder and copy the CardGames.dll file from your flash drive to the Microsoft Games folder on the new PC.

You can launch the game by double-clicking Solitaire.exe. If you'd like to make it easier to launch next time, while the game is running, right-click on the icon at the bottom of the screen and choose Pin to Taskbar.

The game's icon should stay down in the taskbar (to the right of the Start button) so you can launch it quickly.
